The coalition's electoral logo uses lime lettering on a vermilion background, with the word Amplio in capitals. Frente Amplio also has official profiles on X, Instagram, TikTok and BlueSky, and a website, frenteamplio.info, intended to build support and let people sign up to join the campaign. The coalition said it is finalising the presentation of its candidacy, due in Madrid on Saturday 17 October.

Colau told Rac1 and TV3 that neither ERC nor any other pro-independence party had put an independence referendum in Catalonia as a priority in the talks, and she said the name of the coalition could also change. Podemos, whose candidate is Irene Montero, has a cooperation agreement with ERC in Catalonia and has rejected joining the Frente Amplio, while Más Madrid's spokesperson Manuela Bergerot said she hoped a good agreement would be reached. The general election is on 29 November, and coalition registration closes on Friday, 16 October.
